Yo-Yo for Him & Her
His/Hers Yo-yo was designed and manufactured in the MIT Laboratory
for Manufacturing and Productivity (LMP). The design originated from
the desire to 'misplace' a mundane and ubiquitous image in order to challenge
the banality of its message. In choosing the perfect image, we came upon
the male/female toilet logo. Its unisex, gender-equality message targets
the less represented yo-yo consuming population -- women. Of course for
those partial to gender inequality, our yo-yos also come with double female and
double male faces.
are three plastic parts to the yo-yo : an
inner hub, an outer ring, and an artistic centerpiece.
The yo-yo mold designs were created using SolidWorks; these designs were
subsequently regenerated into MasterCAM G code. The molds were
manufactured out of aluminum stock with CNC machines. Both the inner hubb
and the outer ring were injection molded while the centerpiece which bore the
male/female symbol was thermoformed. Once the molds were made and tested, we
ran through production run to produce 100 of each of our parts.
assembly session took place whereby 60 yo-yos were snap-fitted together (the
center piece was held in place by an interference fit) and production tolerances
Note: The goal of this
course, 2.008 was the integration of design,
engineering, and management disciplines and practices for analysis and design of
manufacturing enterprises. Emphasis is on the physics and stochastic nature of
manufacturing processes and systems, and their effects on quality, rate, cost,
and flexibility. Topics include process physics and control, design for
manufacturing, and manufacturing systems. Group project requires design and
fabrication of parts using mass-production and assembly methods to produce a
part in quantity.
